Satellite orbits and clocks are determined using observation data from a global GNSS network together with other parameters such as station coordinates, earth rotation parameters and troposphere ...

This successful demonstration makes it plausible that future lunar missions, whether in orbit or on the surface, could use Earth’s GNSS satellites to navigate and position themselves with.

Measurements of Global Navigation Satellite Systems (GNSS) refer to the electrical phase centers of the GNSS transmitting and receiving antennas. The phase center offsets (PCOs) between the electrical ...

By using a single GNSS receiver, we can achieve global high-precision absolute positioning ... However, PPP is not dependent on local infrastructure and is more suitable for areas without nearby ...

global navigation satellite systems (GNSS) used for orbit determination, remote sensing, and vehicle navigation, and remote sensing of the Earth’s surface, gravity field, oceans, atmosphere and space.

Chinese commercial launch company Galactic Energy successfully sent eight satellites into orbit early Monday with its light-lift Ceres-1 rocket. The Ceres-1 solid rocket lifted off at ...
